I have been super pleased with your plugin, thank you for making a nice product. The only thing that is bugging me is that I cannot locate the css file that will allow me to change the color of .wmle_post_title from a gray to a black so that it is more legible.

Changing the color using the settings is not available in lite version. However you can use custom css in your stylesheet file to change it. It is not good idea to change the plugin css files. This will be over written when new update comes.
